Apple Could Have Already Fixed An Exploit Used For The iOS 7 Untethered Jailbreak

News about the iOS 7 Untethered Jailbreak has been sparse, that is until recently when we received confirmation that the Jailbreak had not been stolen from the Evad3rs and sold to a 3rd party.

Now more news has surfaced on the Jailbreaking front, but unfortunately it doesn’t look to be positive.

iOs 7 Untethered Jailbreak

Shortly after the release of iOS 7.1 beta , the developer behind Sn0wbreeze and other tools, iH8Sn0w took to Twitter to announce that iOS 7.1 has fixed the ”mobilebackup2 exploit to write to /var via the MediaDomain symlink.” The tweet came as a response to someone asking if it was safe, in iH8sn0w’s opinion, to upgrade to iOS 7.1 beta 2.

Obviously this is a very technical tweet that even I have a hard time understanding, so I will turn it over to jailbreak tweak developer phoenixdev, known for tweaks Music Controls Pro and Shrink to explain what this means.

Mobilebackup2 is the system used to generate your user backups, as well as place them back on the phone. But it’s designed for only particular folders in the user directory.

It has been used in years past via path walking (prepending ..’s to walk up the directory tree) to let us put files in other places in the /var partition. I’m guessing that they found they could do something similar by creating symlinks to other places on the /var partition.

Actually, I’m not guessing. I know you could do that because a failbreak I once made used that.

P.S. root partition = where the OS is installed; mounted at the base of the filesystem ( / ). /var partition = where the user data is; mounted at /var. When you update your phone, the root partition is overwritten while the var partition stays around. When you restore your phone, both partitions are wiped.

Even Stefan Esser, better known by his alias on Twitter as i0n1c has taken to Twitter to say that Apple has indeed patched some exploits intended for the iOS 7 Untethered Jailbreak in iOS 7.1.

The last update we heard on the progress of the Jailbreak came from Pod2G a few days ago who said “the jailbreak stuff is moving on, but slowly.” With today’s news of exploits potentially being patched, however, our advice would be to hold off on updating to iOS 7.1 until we get confirmation from one of the Evad3rs on whether or not it is safe to update (like you should be doing every new firmware release).

    Phew, and I was about to update.

    I believe the jailbreak days are over. I am going to update to iOS 7.0.4 and I’m done with Apple products. Next year I’m switching to Android and rooting.
    Funny, he photo with this story appears to a Samsung Galaxy, not an iPhone.

    That’s because it has a theme on the iPod. It has cydia on it so it’s jailbroken or shopped.

  • Dani Hayes

    I upgraded to iOS 7.0.4. Only missing few tweaks.

    you cant do anything with rooting all you can do is mess around with pictures and change icons and that sort of thing. if you want to change root apps or add root apps you need an exploit so that device is able to run unsigned code (THATS WHAT THE JAILBREAK IS FOR!)

    Actually you can run unsigned apps with rooting your phone andbunlocking your boot loader, pretty simple in most android phones
